Articles like his do a great job of communicating change, but a very poor job of communicating threat. I'm going to be unpopular and say I still can't see why the metrics being listed here rate higher consideration than all the threats that could reasonably be imagined over the next 40 years. The risk of running out of fossil fuels without being prepared is much more threatening than the statistics listed.<p>I'm going to single out "Sea levels are rising." for special mention - entire cities can be constructed in 40 years (I'm thinking Shenzhen); 9 inches over a century isn't that scary in context of all the other radical change that has happened over the same period. There was a period in there where nuclear annihilation was an imminent threat. Nuclear annihilation is still a concern.<p>It is obvious the situation is changing, it is not obvious in this article that any of the changes are important over the timeframe given. There is always going to be radical change over a 20 year period that we have to roll with.
